This trail starts from Nant Cwm Llwch campsite and car park and is a long, gradual walk through a beautiful valley. The path from the campsite is well-marked and obvious as it makes it way through the woods and out onto open land. Be sure to visit the pretty little lake, Llyn Cwm Llwch, before you begin climbing up onto the ridge.. The trail begins from the Nant Cwn Llwch Car Park. It then follows a trail leading south toward Corn Du.. Beginning from the north, at the Cwm Gwdi Car Park, this walking route enjoys incredible views of Corn Du, Cribyn and Fan y Big as you ascend the highest peak in south Wales. This direct route to Pen y Fan is a fantastic walking option.

The trail starts at the Cwm Cwdi Car park to the north of Pen y Fan, along a narrow lane and takes you along the base of the mountains before starting the ascent of the edge of the Nant Sere gully. Reaching the head of the cwm, cross the Nant Sere and make your way up the northeastern ridge of Crybin.. For an alternate version, you can also start in the next valley over beneath Llyn Cwm Llwch and the Nant Cwm Llwch car park. This route follows the river up from the car park, before emerging out onto the hillside beneath Llyn Cwm Llwch. The beautiful tarn lake is a great place to stop for a snack before the climb really begins.
